AIR-INTAKE AND PBIMING DEVICE.

Application filed June 14,

To all whom it may concern: 7

Be it known that I, (inonon LANE, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented new and. useful Improvements in Air-Intake and Priming Devices, of which the following a specification.

This invention relates to an air intake and priming device for internal combustion engines, and the object is to provide a device which may be carried on the steering column or dash-board of a motor car, being connected by tubing with the intake manifold, and being adapted for use, when provided with a priming fluid, as a priming levice, and capable of use at other times as an auxiliary air intake.

A further object is to provide, in connection with a suitable tubular element between the dash-board and intake manifold, a casing to be mounted on said board, and an element constituting a valve member cooperating with the casing and adapted to control the admission of fuel to the engine, or the admission of air, as the case may be.

A. still further object is to provide a particular type of valve member, whereby the purposes specified may be realized.

.a still further object is to provide a particular form of connection between the in take manifold and the tubular element connected with the casing on the dashboard.

ln the drawings, Figure 1 shows the device in side elevation, and connected with an intake manifold; Figure 2 is a front elevation of the device independent of its connections; Figure 3 is a vertical section; Figure a is a vertical section at an angle of 90 degrees from that of Figure 3; Figure 5 is a perspective view of the valve member; Figure 6 shows an elbow for connecting the device with an intake manifold.

With the foregoing and other objects in view, the invention consists in the novel construction and arrangement of elements described and claimed, it being understood. that modifications may be made within the scope of the claims, without departing from the spirit of the invention.

The intake manifold 10 has connected. therewith an elbow 11 provided with the threaded portions 12 and 13, one of these threaded portions being connected by a coupling 14: with the tubular element 15, and the latter extend'ng to the connection 15' in.

1921. Serial no. 477,492.

the casing 16. The port through this connection is designated 17.

A slot 18 is provided in one side of the casing, and accommodates a handle 19 of the valve member 20. This valve member is of disk form having a flange 21, cutaway as shown at 22 toprovide a tapered portion 23 and a shoulder 24:, the tapered portion permitting of partial closing of the port 17 prior to fully closing that opening.

The disk or valve member is further pro vided with apertures 25, and when the engine is running at a considerable speed, and it is desired to admit more air, this valve may be employed. for that purpose, and may further be employed for admitting air for braking purposes when the car is proceeding down grade with the throttle closed.

The casing is provided with a central boss 26 receiving a screw 27, the end of which passes into the valve member. A coiled.

spring 28 surrounds the boss and bears against the inner surface of the valve member, producing suflicient friction to retain the valve in a given position.

Priming fluid may be introduced when clesired through the ports shown, and preferably through ports 30 and 31, these ports being in registration when the handle 19 is in the position shown in Figure 3 (port 17 then being open).

Connected with the elbow and projecting into the manifold is a tubular element 34 having longitudinal slots 35 therein, permitting of the passage of air into the manifold, as through a flat nozzle or a series of such nozzles. The end 36 is also open.

.t will be understood that the auxiliary air supply is intended to economize fuel and to produce a mixture giving the best results under given conditions.

What is claimed is:

1. In an auxiliary air intake device, a casing having a port in the wall thereof and also having a slot in said wall, a valve member of disk form having apertures therein and having a flange provided with a cutaway portion, and a handle for said valve projecting through the slot in the casing.

'' 2. An auxiliary air intake device, comprising a casing having a port in the wall thereof adapted to place the casing in communication with an intake manifold, the casing also having a segmental slot in one wall thereof, a valve member of disk form having apertures therein, and having a 'ilzu'igc provided with 21 cutaway portion formed with a tapered well and a shoulder, the tapered Well cooperating with. the aforesaid port, and an operating device connected with the valve member and passing through the aforesaid slot. 3. An auxiliary air intake device, comprising a casing having an inlet and an outlet port and having a slot in one Well, a

10 valve member of disk form mounted in the casing and provided with apertures, said valve member also being provided with an inlet port and with an outlet port one oiwhich has an inclined wall extending in a direction circninferentially of the valve, and an. operating device connected with the valve member and projecting through the aforesaid slot.

In testimony whereof I aflix my signature.
